This is just speculation, of course, but do you guys think maybe someone seriously might have done something to the servers?
I mean, I can understand an unexpected crash+restart. Or even a crash+fix+restart. But I really think something went terribly wrong.

And everyone here knows that there have been plenty of trolls who seem like they would do something like this just because they didn't like the game.

3) Massive server crash due to the overload, related to the 149M (?) patch. To me, very likely, they still have problems when both Americans and Europeans are online. I won't be surprised if the server has troubles again tomorrow after 8pm GMT.
